UNITED STATES JAMES WILLIAM GARRETT, OF ELK CITY, OKLAHOMA.

COTTON-CHOPPER.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed December 26, 1908. Serial No. 469,349.

To all whom it may concern:

Be it known that I, JAMES W. GARRETT, a citizen of the United States, residing at Elk City, in the county of Beckham and State of Oklahoma, have invented certain new and useful Improvements in Cotton-Choppers, of which the following is a specification, re erence being had to the accompanying draw ings.

This invention relates to improvements in cotton choppers and consists of the novel features of construction and the combination of parts hereinafter fully described and claimed.

The object of the invention is to provide a simple and practical machine of t iis character in which the shaft carrying the rotary chopping hoes may be readily adjusted.

The above and other objects of the invention are attained in the construction illustrated in the accompanying drawings, in which- Figure cotton chop tical longituc inal section; view; Fi

1 is a side elevation of the improved ing machine; Fig. 2 is a ver- Fig. 3 18 Fig. 2; Fig. taken on the plane indicated by the line 5 5 in Fig. 2; F

ig. 6 is a side elevation of the wheel carrying the chopping hoes; and Figs. 7 and 8 are detail views of the bearing for the axle of the supporting wheels.

In the drawings 1 denotes a main frame consisting of upper and lower pairs of longitudinal side bars 2, 3 united by upright side bars 4, the lon itudinal side bars of each air being unted by he rear end of the frame is support-ct by two ground wheels 6, 7, the former of which is fixed to one end of an axle 8 so as to cause the latter to rotate with it and the other of which is loose upon the opposite end of the shaft 8 and retained thereon by adjustable collars 9. The shaft 8 is journaled in two bearings 10 arranged corners of the frame and each consisting 0 an upper bearing member 11 formed wit an attaching shank 12 and circular bearing recess on one is a loop 13 and on an apertured lug 14. sists of a lower bearing member curved bearing recess horizontal cross bars 5.

a top plan 4 is a detail cross section taken on the p ane indicated by the line 1 1 in 5 is a detail horizontal section upon the lower rear with a semiside of which the other side of which is Said bearing also con- 15 having a on one side of which is the loop 13 and on the other side of which is an apertured lug 17 engage the lug i=1 so that the it 18 may be passed through the apertures in the two lugs. The front end 0 the frame is adapted to be supported by the draft aninnls attached. to a draft tongue or OOlB 19 secured at its rear end to the center of the upper cross bar 5, as shown at 20, and between the converging forward ends 21. of the two upper longitudinal side bars 2, which ends 21. form diagoml braces, as seen in Fig. 3. on the top of the tongue 1. is pivoted a double tree 22 from which loosely depend links 23 which have their lower ends connected by chains or the like 24 to the projecting forward end of the two lower longitudinal side bars 3.

22 may, if desired, be located beneath the tongue. The links 23 are formed with vertical series of apertures 25 to receive hooks or other fastenings on swingle trees 26 so that the latter may be adjusted vertically on the links 23.

The chopping of the cotton plants is done by means of a series of circumfcrcntially ex-. tending hoe blades 27 secured on the ends 0" arms 28 projecting radially from the rim 29 of a wheel 30, which latter has a ably arranged haft 32 and adapted to be secured upon a s by a set screw 33 r adapted to fastening b in an adjusted position thereon as seen in F' (5. ihe shaft 32 is arranged cen'rally an longitudt nally beneath the main frame 1 and is rotatable in bearings carried by a vertically adjustable hoe supporting frame The latter consists of two inverted \I-shaped or U- shaped members 35, the closed upper ant converging ends of which are united to the ends of a longitudinal bar 36 and the diverging arms of the diverging members 35 are united to two transverse bars 37, 38, he ends of which slide in vertical slots 39 formed in the depending lower ends of the upright bars 4. Said projecting ends of the cross bars 37 38 are united by longitudinal slide bars 40 which serve to strengthen the hoe supporting and adjusting frame 3 1. Said hoe carrying shaft 23 has its forward end journaled in a centrally arranged bearing ti on the bar 37 and its rear end is journaled in a bearing 42 and a short cross bar 43 connecting the ends or arms of Ushaped member 44 which is fastened by clips 4:5 or other suitable means to the cross ar 38, as
